The data were grouped by the age (ie, ≤ 29, 30– 35, and ≥ 36 years old) in which embryonic chromosomal abnormality rate, and abnormal distribution of chromosome number in abortion tissue of 294 patients.Results: The examination of 516 samples of spontaneous abortion tissues showed that the chromosomes of 294 samples were abnormal, and the abnormality rate was 60.97%. Among 294 samples with chromosomal abnormalities, 136 (89.47%) samples had numerical chromosomal abnormalities, 15 (9.87%) samples had structural chromosomal abnormalities, and 1 (0.07%) sample had uniparental disomy. A total of 308 couples voluntarily underwent peripheral blood chromosome analysis. The results showed that 56 couples had abnormality in one or both spouses, and rate of embryonic chromosomal abnormality in these 26 cases with chromosomal abnormalities was 100%.Conclusion: Numerical and structural chromosomal abnormalities are among the important causes of embryonic arrest, while the increase in age could also be a high-risk factor for embryonic chromosomal abnormality. Therefore, examination of the karyotypes of embryo chorionic villus may help understand the reasons of embryonic arrest, which could provide important guidance for more genetic counseling for patients with early spontaneous abortion, as well as improving the preconception preparation.Keywords: spontaneous abortion, villus tissue, HLPA test, chromosomal abnormality
